“We are sorry to hear about the crack on your camera lens. Unfortunately, Samsung Phone warranties do not cover cosmetic damage. If you are enrolled in Samsung Premium Care, you can set up a repair at an authorized Samsung Repair Center or Partners,”
checked it the answer was in the comments bro. " You explained your problem in such a way that you literally answered your first question.
You shake the phone and you hear a rattle. You equated that to the mechanism that allows OIS.
You open the camera app and you still hear it only quieter. Well that's because the mechanism is now being controlled by the camera app so it's trying to keep it stable and centered.
The camera module is pretty small so the force of shaking the phone is bound to make it make some noise.
When you switch modes the aperture is closing opening and moving on it's axis slightly. So it makes some noise if you are listening but it's hard to gauge your definition of "violently" when it's so small and we can't see your device. "
This same problem arised with my my Galaxy S10 Lite. considering it has a similar design to S20. A crack developed automatically across the back camera glass. The phone wasn't mis handled at all.
